Gall Wasps, Sawflies, Gall Midges and Scales…

A few years ago I wandered around northeastern North Dakota and northwestern Minnesota collecting images of selected common Gall Wasps, Sawflies, Gall Midges, and Tortoise Scales.  These images are collected and archived below with the hope that they may one day be useful to local naturalists.  Enjoy!
